Unlocking ending 15

[KLightningflik]

So I got Ending 14 earlier today for beating ??? with the polaroid, but how do you get the negative? I beat Shoel twice now and nothing has changed.
With the polaroid you could see the picture on the save file screen slowly being pieced back together...but it still just shows the skull and "The end" for me. :\

Negative goes below the polaroid when being built, kill Satan 5 times to unlock it even when it isn't on save file.

Ok, I just wanted to be sure that I still only needed to beat Shoel 3 more times. There's nothing to really show your progress toward it.

If you fought Satan before Isaac, you can see progress on the Negative.

Infact, if you split your wins between Isaac and Satan but before unlocking Polaroid, it becomes a pretty weird collage.

Got the Negative, kinda weird but ok. Now just need to do another full run for ending 15.

How to unlock the polaroid? Do you need to kill Isaac 6 times?

The Lamb never struck me as a difficult boss. He was just kinda...weird. Just died really quickly.

By the time I got to him I only had half a heart, it's the grind to get there.
